Overview
The LTC2630CSC6-HM8 is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It features an integrated precision reference providing a full-scale output of 4.096V and operates within a supply voltage range of 4.5V to 5.5V. The device utilizes a rail-to-rail output buffer and communicates via a 3-wire SPI/MICROWIRE compatible serial interface with clock rates up to 50MHz. Key specifications include a maximum integral nonlinearity (INL) error of ±0.5 LSB, a typical settling time of 3.7µs at 5V, and a power-down current of 1.8µA maximum for C and I grades. It is housed in a compact 6-lead SC70 package.
Feature Summary
- Integrated 4.096V Precision Reference with 10ppm/°C drift
- Rail-to-Rail Output Buffer with Guaranteed Monotonicity
- 3-Wire SPI/MICROWIRE Serial Interface (up to 50MHz)
- Power-on Reset to Mid-Scale (HM suffix)
Applications
- Mobile Communications
- Process Control and Industrial Automation
- Automatic Test Equipment
- Portable Equipment
- Automotive
Procurement Notes
Verify the specific ordering suffixes against the manufacturer's official documentation to ensure correct resolution, temperature grade, and reset configuration. Confirm that the supply voltage requirements (4.5V to 5.5V) align with the target system design before procurement.
Selection Notes
Select this component when a low-pin-count, single-channel DAC with an internal reference is required. The HM suffix indicates a mid-scale power-on reset, which differs from the HZ suffix that resets to zero scale. Ensure the application supports the 4.5V minimum supply voltage required by the 'H' grade family.
Part Context
This part belongs to the LTC2630 family of single-channel DACs available in 12-, 10-, and 8-bit resolutions. The 'C' denotes the commercial temperature range (0°C to 70°C), while 'H' specifies the 4.096V full-scale internal reference. The 'SC6' indicates the 6-lead SC70 plastic package.
Replacement Considerations
Direct pin-compatible replacements within the same family include LTC2630CSC6-HZ8 (Zero-scale reset) or LTC2630CSC6-LM8 (2.5V reference). Cross-family replacements require verification of interface compatibility and voltage levels.
